Hi Gary Columb,
Welcome to the Microsoft Q&A forum.
I understand how confusing it can be when your microphone is detected, but the test doesn’t seem to play back any sound.
Here are some quick checks that you can consider:
- Go to Settings > System > Sound > Input and make sure the intended microphone is selected. Speak and check if the input level bar moves.
- Open Settings > Privacy & security > Microphone and ensure:
- Microphone access is On
- Let apps access your microphone is On
- Let desktop apps access your microphone is On
- In Sound > Input, select the microphone and set Input volume to around 80–100%.
If the test still plays no sound, please try the checking steps from Q&A Assist's answer.
Also consider turning off audio enhancements to check
- In the microphone’s properties, switch Audio enhancements Off, then restart the PC.
